For the traditional EIT and ATS in the un-modulated systems, it is widely acknowledged that: ATS exhibits a wide non-interference transparency window between large Stark splittings induced by a strong field [1]}, [2]}, while EIT exhibits a narrow transparency window induced by destructive quantum interference (QI) between the Stark splittings [3]}. In the weak probe field approximation, according to Ref. [4]} the absorption of the probe field is determined by the first-order coherence of the probe transition and is given as
\(\text{Im}(\rho _{10})_{\text{QI}}=\frac{\Omega _{p}}{4B}[(\Delta -\frac{\Omega _{c}}{2})^{2}\Gamma +(\Delta +\frac{\Omega _{c}}{2})^{2}\Gamma +2A]\)
